Title: Composite ring roll for angle rolling
Inventor: NAKAGAWA YOSHIHIRO
IPC: B21B1/08
Filed: 1985-08-05
Abstract: PURPOSE:To reduce a price of a composite ring roll for angle rolling and to extend roll life by embedding an annular ring of an excellent wear resistance material and of an angle-shaped section into a base body with the periphery of the ring being cropped out and joining the ring with the body diffusely. CONSTITUTION:Composite ring rolls 1a and 1b are made up of ring bodies 2a, 2b for rolling and ring base bodies 3a, 3b, respectively. The ring bodies 2a and 2b are formed by sintering high alloy powders having an excellent wear resistance; the periphery of the ring bodies 2a and 2b contacts with a rolling stock and rolls and forms the stock into an angle. The ring base bodies 3a and 3b are of a low carbon low alloy steel having ferrite base and embedding grooves 4a and 4b are formed on the periphery of respective annular rings and irregularity is formed on the embedding plane. The embedding grooves 4a and 4b are press filled with powders of high wear resistance material into an angle shape and the powders are sintered and joined with the grooves 4a and 4b diffusely. Therefore, joining strength is increased so that the ring rolls 1a and 1b are fixed to a shaft by shrinkage fitting, welding, or bolting.

Title: Production of chilled cam shaft by remelting
Inventor: FUKUMIZU TOSHIHARU
IPC: C21D9/30
Filed: 1985-08-08
Abstract: PURPOSE:To suppress the sagging of a molten pool and to increase the max. chill depth by interrupting the melting effect with time to solidify the molten pool and restarting the melting effect so as to superpose chill layers at the point where the molten pool generated in the stage of melting is liable to sag by gravity. CONSTITUTION:A cam shaft 1 is oscillated by a driving machine 62 for oscillation without being turned and is preheated by a TIG torch 38. The cam shaft 1 is then rotated and is melted by a TIG arc from the base circular part of the cam 2. The treatment is executed over the entire periphery. The rotation of the cam shaft 1 is stopped and at the same time, the melting current is changed over to non-melting current to allow the molten pool to solidify when the point of the max. sagging angle comes to the position right after a torch 38 in the mid-way from the base circular part of the cam to the nose part. The non-melting current is then reset to the melting current and the melting is again executed in said position so that the chill layers are made continuous. The rotation of the cam shaft 1 is thereafter restarted. The sagging of the molten pool by gravity is thereby minimized and the max. chill depth is increased.

Abstract: PURPOSE:To enhance the reliability of a connection part by sure connection with solder by a method wherein a projection or a hole is formed to an outer lead at the part of abutment against an electrode provided on the substrate. CONSTITUTION:The outer leads 3 and 13 of a semiconductor device 1 connected to the mounting substrate 6 at the bent part of the outer leads 3 and 13 are provided with the projection 18 or hole 8 at the part of abutment against an electrode 7 of the mounting substrate 6. For example, in the case of forming the hole 8 at the position where the lead 3 comes to abutment against the electrode 7, mounting to the substrate 6 is carried out by first swelling a solder 5a at the part of the electrode 7 of the substrate 6, and then bringing each lead 3 of the semiconductor device 1 into abutment against this part. At this time, the solder 5a partly penetrates through the hole 8 to the inside of the lead and spreads along the inside surface of the lead 3. Therefore, solidification on cooling enables the sure connection of leads 3 to electrodes 7 because the solder 5a holds the lead 3 from its inside and outside via hole 8.

Abstract: PROBLEM TO BE SOLVED: To reduce an interfacial roughness and to improve the surface property by forming a non-magnetic layer being a lower lamination of a magnetic recording medium by applying a coating liq. of a non-magnetic powder, a binder and a solvent on a flexible non-magnetic supporting body.

In this way, a good surface property is obtained. The binder excellent in adhesion and wear resistance at the time of applying on the flexible non-magnetic supporting body is added. A thin material can be used as the flexible non-magnetic supporting body since the three-dimensional hexagonal network is formed and the non-magnetic layer being the lower lamination is rigidifyed by using the binder having a functional group and a crosslinking agent capable of forming a three-dimensional hexagonal network by reacting with the functional group at the non-magnetic layer being the lower laminated and crosslinking and curing the binder after applying.  In this way, the magnetic recording medium smooth in surface and suitable for high density recording is obtained.
